COATING-TRAY.

SPECIFICATION forming part of Letters Patent No. 704,592, dated July 15, 1902. Original application filed November 8,1899, Serial No. 736,244.Divided and this application filed January 30,1901. fierial To all whom,it may concern.-

Be it known that I, PERCY B. TAYLOR, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new anduseful Improvements in Coating-Trays forApparatus for the Desiccation of Eggs; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to figures of reference marked thereon, which form a part of thisspecification.

My present invention, which is a division of my former application for apatent filed November 8, 1899, Serial No. 736,244, relates generally toimprovements in apparatus for the desiccation of eggs or other material;and theinvention has reference more particularly to a novelconstructionand arrangement with a rotating drum or wheel and a coating-tray inwhich the egg-batter or other material for desiccation is contained forapplication in the viscid or glutinous state to the drying-surface ofthe drum or wheel or other equivalent device in an approximately evenand unbroken film or sheet.

The primary object of thisinvention, therefore, is to improve thegeneral arrangement and construction of revolving drum or wheel andfeeding-tray for the desiccation of eggs or other materials and,furthermore, to provide a novel means for delivery of the viscid orglutinous material for the purpose of manufacture in an even andunbroken sheet from the coating-tray in a manner easily controlled andregulated without the least possible Waste of the material and with butvery little cost of machinery or apparatus.

This invention therefore consists in the novel construction ofcoating-tray to be hereinafter fully described; and, furthermore,thisinvention consists in the several novel arrangements and combinations ofparts, as well as in the details of the construction of such parts, allof which will be more particularly set forth in the accompanyingspecification and then finally embodied in the clauses No. 45,302. (Nomodel.)

of the claim, which form a part of this specification.

The invention is clearly illustrated in the accompanying drawings, inwhich- Figure l is a horizontal section of a drying drum or wheel,illustrating in connection therewith one means for driving the same andthe application to its drying-surface of a coating-tray made accordingto the principles of my presentinvention. Fig. 2 is a side elevation ofa portion of the rim of the drying drum or wheel and a supporting-framewith the coating-tray in its operative position against the surface ofthe said drum or wheel, and Fig. 3 is a front view of the said frame andtray. Fig. 4 is a vertical section of another form of coating-tray madeaccording to the principles of this invention, the same beingrepresented inits operative contact with a portion of the surface of thedrum or wheel. Fig. 5 is a front View of the said coating-tray with aportion of a supporting-frame on which said tray is placed; and Fig. 6is a top or plan view of the said tray, on an enlarged scale, said Viewillustrating in connection with the said tray a different means ofadjustment. Fig. 7 is a side view of the said tray and the means of adjustment connected therewith. Figs. 8, 9, and 10 are diagrammaticalrepresentations of portions of the tray and differently-formedcontact-strips, which are forced against the surface of the drum orwheel and prevent the escape of the viscid or glutinous material withinthe tray from its side and bottom edges when in operation against theface of the said drum or wheel.

Similar characters of reference are employed in all of the saidabove-described views to indicate corresponding parts.

In the said drawings, 1 indicates anysuitably-constructed drum or wheelcomprising the hub 2 and spokes or arms 3, to which is secured inanydesirable manner a suitable cylindrical body 4, which forms adrying-surface and onto which the material to be desiccated is to beapplied in the manner hereinafter fully set forth. The said wheel ispreferably made of wood; but any other suitable material may beemployed, and it may be differently constructed. The said drum or wheelis supported upon a shaft 5, which rotates in bearings 6 of suitablesupports or pedestals 7, as will be clearly understood. Any suitabledriving means may be employed for causing the rotation of the said drumor wheel 1, the preferred mechanism being a toothed ring 8, which isarranged against one side of the said drum or wheel, substantially inthe manner represented in Fig. 1 of the drawings, and a pinion 9, gearedwith the same, said pinion 9 being arranged and secured upon a shaft 10,which rotatesin bearings 11. Upon this shaft 10 is secured a loosepulley 12 and a fast pulley 13 for actuating the shaft from a belt inthe usual manner. Suitably placed at one side of the cylindrical body 4of the said drum or wheel 1, as will be noticed more particularly froman inspection of Figs. 1 and 2 of the drawings, isa supporting-frame ofany usual construction, which consists, essentially, of the two sideframes or standards 14 and a top 15 for the placing thereon of acoating-tray 16. The said tray consists, essentially, of an inclinedbottom 17, a back 18, and the sides 19, being left open at the top andfront and the forward edges of said tray being made tapering,substantially as shown, so as to conform to the cylindrical surface ofthe drum or wheel 1. The said coating-trayis adjustable toward or fromthe face of the cylindrical body4 of the drum or wheel 1 for thecompression of rubber or other flexible contact-strips 21 against thesaid body 4 of the drum or wheel 1 to prevent any loss of the egg-batteror other material at the sides and bottom edges of the tray 16.

In Figs. 8, 9,- and 10 of the drawings Ihave illustrated various formsof flexible contactstrips which may be employed in connection with thetray, the forms represented in Figs. 8 and 9 being the preferred formsof strips. The strip 21 (indicated in said Fig. 8) is tubular incross-section and has its portions 22 doubled upon themselves andarranged in a groove 23, formed in the edges of the bottom 17 and in theedges of the sides 19 of the tray, substantially as illustrated, beingsecurely held in position against displacement when the strip is insliding contact with the revolving surface of the drum or wheel 1 by asuitable plate or bar 24, which is secured in position by means ofscrews or otherwise and has the holding edge 26, which firmly bites orgrips the portions 22 of the strip 21 to prevent any possibility of suchdisplacement. In the said Fig. 9 I have illustrated a flexible strip 21of a slightly-different form in cross-section and a different means ofsecuring this strip in position. In this construction the strip 21 hasits portions 22 firmly wedged in a recess or a cut-away portion 29 inthe bottom and sides of the tray, the said parts being securely held inplace by means of a plate or piece 27 and the screws 28, as illustrated.The said flexible rubber strips 21 and 21", as will be clearly evident,may, if desired, be filled with air, so as to 'provide a pneumaticrubber edge or binding at the side and bottom edges of the tray. In someinstances I may secure in the recess 23 a solid and flexible strip 21",which has its portions 22" arranged in the recess 23 and is held inplace by the clamping or holding end 26 of the plate or bar 24. Ofcourse it will be evident that any other suitable forms of flexiblestrips may be employed with the said tray 16, and the said strips may besecured in position by any other means.

In Figs. 1, 2, and 3 of the drawings I have illustrated one form ofadjusting mechanism to be employed in connection with the tray 16 forautomatically forcing the contact-strips on the bottom and side edges ofthe tray in close contact with the cylindrical portion 4 of the drum orwheel 1 and causing the coatingtray to adjust itself to any inequalitiesin the cylindrical body 4 during the rotation of the drum or wheel. Asshown in the said figures, I have secured in position upon the top 15 ofeach standard or frame 14 by means of suitable bolts 30 or in any othersuitable manner a plate 31. Each plate 31 is provided with theupwardly-extending guide portion or way 32, and each plate 31 is alsoprovided with an upwardly-extending post 33, having an eye or perforatedboss 34. Suitably secured upon each side 19 of the coating-tray 16 bymeans of screws 35 or in any other manner is a plate 36, provided withthe downwardly-extending part 37 and a rib 38, fitted and slidablyarranged in the way or guide 32, substantially as illustrated. The saiddownwardly-extending part 37 of each plate 36 is also provided with aperforated ear or lug 39, extending at a right angle, or approximatelyso, from the said part 37, in which is loosely arranged a rod or bolt40. This rod has its one end secured within the eye or perforated boss34 either by means of a pin 41 or in any other manner and has upon itsopposite and screwthreaded end 42 an adj usting-nut 43. Encircling eachrod or bolt on that portion between the ad j ustin g-nut 43 and theperforated ear or lug 39 of the side piece 36, secured to the tray, is acoiled spring 44, the coils of which will constantly cause the flexiblestrips which are secured in the edges of the tray, as hereinabove setforth, to be in positive contact with the cylindrical part 4 of therotating drum or wheel 1, and thereby prevent any loss of the egg-batteror other material at the sides and bottom of the tray 16, as will beclearly evident.

In Figs. 5, 6, and 7 I have illustrated another means for adjusting thetray to or from the face of the cylindrical body 4 of the drum orwheel 1. In this construction I have secured to the outer face of eachside 19 of the tray 16 by means of a bolt or screw 45 or in any othersuitable manner brackets or plates 46, each plate having a shoulder 47extending at a right angle, or approximately so, from the body of eachplate 46, and firmly secured upon the top 15 of the side frames orstandards 1st by means of bolts or screws 18 are a pair of brackets orplates 49, on each of which is an upwardly-extending arm or lug 50,having a screw-threaded hole for the reception of a suitable adjustingscrew or bolt 51,which can be screwed against the shoulder or plate 47of the respective plate 46 at each side of the coating-tray. Suitablysecured against the outer faces of the two sides 19 of the tray 16 bymeans of screws 52 or in any other suitable manner are guide-plates 53.Each guide-plate 53 has a shoulder 54 formed at a right angle thereto,or approximately so, said shoulders being provided with slots 55 or theequivalent thereof,whereby said plates 53 can be slidably arranged overcertain studs or pins 56 in the top 15, and the coating-tray can therebybe held in its adjusted position against the rotating surface of thedrum or wheel 1 by means of suitable thumb-pieces 57 on the upperscrew-threaded ends of the said studs or pins 56. It will thus beclearly evident that by slightly unscrewing the said thumb-nuts and byturning the adjusting screws or bolts 51 the tray 16 can be readilyforced in aforward direction toward the body of the drum or wheel tocompress the contactstrips at the bottom and side edges of the tray andcause the free edges of the bottom and sides of the tray to close upagainst the moving surface of said body at of the revolving drum orwheel 1, and thereby provide a batter-receiving receptacle from whichthe batter or other material is readily applied in a thin and evencoating upon the surface of the said drum or wheel, upon which thematerial is then thoroughly dried by the extraction of all moisture whena current of dry and heated air is forced around the part 4: of the drumor wheel through a surrounding airboX 58. (Indicatedin Fig. 1 of thedrawings.)

Of course I am aware that changes maybe made in the various arrangementsand combinations of the several parts herein set forth, as well as inthe details of the construction of the same, without departing from thescope of my invention. Hence I do notlimit my invention to the exactarrangements and combinations of the various parts as herein describedand as illustrated in the'accompanying drawings, nor do I confine myselfto the exact details of the construction of such parts.
